CNG PRMS
This series of pressure-regulating boxes is primarily designed for medium and low-pressure gas transmission and distribution systems. Each unit includes a filter, pressure regulator (with self-shutoff and release functions), ball valve, pressure gauge, and enclosure. The box features a compact structure, easy maintenance, and reliable safety performance. It is suitable for use in civil buildings and at small to medium-sized sites, such as apartment complexes, hotels, and restaurants. Additionally, it can be used with low-pressure gas boilers and small direct-fired turbines. The enclosure is manufactured from stainless steel, spray-coated cold-rolled steel or fiberglass.
